Abstract

Abstract Abstract Background: Antibodies have emerged as essential tools of biomedical researches and are of great commercial and medical values. They are the fastest growing product segments of the pharmaceutical industry. Polyclonal antibodies are antibodies that secreted by different B cell lineages within the body. In this study production of polyclonal antibody against Goatpox and Sheeppox virion in rabbit was performed and subsequently; it will be used as the development of ELISA for detection of poxvirus in different species of animals. Results: After 0.5mg/ml of the whole virion of the poxvirus was injected subcutaneously at multiple sites, the blood was collected at an interval of 14 days and antibody titration was conducted. GTPV A27 antigen was coated and indirect ELISA method was used for the titration of antibody then the mean of OD values for positive and negative results were analyzed by Microsoft excel window 7. The blood was collected and serum was prepared for IgG purification. The IgG was purified by Ammonium sulfate precipitation method which was dialyzed against 5lire PBS overnight at +4oc. The protein concentration was determined spectrophotometrically at 280nm wavelength and estimated as 2.29µg/µl and 2.1...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
